H13 Steel

H13 Steel

Steel name: H13
Diagram No.: 2171
AISI/SAE designation: H13
Chemical composition in weight %: 0.40% C, 0.95% Si, 0.35% Mn, 5.20% Cr, 1.50% Mo, 0.90% V
Steel group: Hot work tool steels
Properties: No data
Applications: Dies for casting of aluminum or other light metals. Extrusion dies for aluminum or other nonferrous alloys. Forging dies and die holders for steel or other ferrous and nonferrous alloys. Hot shearing blades. Tools for hot pressing. Wear resistance parts, when nitrided. Injection or other molds for plastic.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: Two preheats 1200°F (650 °C) and 1550°F (840°C), normally in two pre-heating steps. Third preheat for big blocks over 12 inches 1650 °F (900°C). Austenitizing temperature: 1870–1920°F (1020–1050°C), normally 1870–1885°F (1020–1030°C).
Tempering: Choose the tempering temperature according to the hardness required by referring to the tempering graph. Temper twice with intermediate cooling to room temperature. For big blocks over 12 inches, a third tempering is recommended. Holding time at temperature minimum 2 hours. Do not temper in the range 800–1020°F (425–550°C).
Diagram note: Above tempering curves are obtained after heat treatment of samples with a size of 15 x 15 x 40 mm, cooling in forced air. Lower hardness can be expected after heat treatment of tools and dies due to factors like actual tool size and heat treatment parameters.
